I have a question about my 1979 240D, original OM616 engine. The valve cover has a hose that goes from the top of the valve cover directly into the intake manifold, right under the air cleaner. I think that a decent amount of oil is going through this hose and is being burned in the engine. When I look into the manifold I can see standing oil down in it. I took the air cleaner off and there is oil buildup all around the top of the manifold. The engine has pretty good blowby, but not enough to blow the oil cap off if it is unscrewed. It smokes a little when it is cold, kind of a grey smoke. Doesn't really smell like oil as much as just strong diesel scent. Still, I burn a quart every 400 miles or so, and I wonder how much is just going into the intake.

Anyway, can I get an oil seperator for this car? Was/is one stock on this engine? If anyone else has had a similar situation I would love to hear about it. It would be nice to not drink so much oil too, if this is really where it is going. Thanks for your advice.
